fix: disable eslint for Vue 3 type shim (for now)

See https://github.com/vuejs/vue-cli/pull/6023

It's not the ideal solution, though.

In the long run we should have the shim built-in (either in this plugin
or in the `vue-loader` package), for which ESLint rules should be
properly applied, and the user can simply import that shim module.
